Answer:
70 percent of what number is 90?
90 is 70% of 128.57
Steps to solve "90 is 70 percent of what number?"
We have, 70% × x = 90
or,
70
100
× x = 90
Multiplying both sides by 100 and dividing both sides by 70,
we have x = 90 ×
100
70
x = 128.57
If you are using a calculator, simply enter 90×100÷70, which will give you the answer.
Answer: 70 % of 90 = 63
Step-by-step explanation:
70 % x 90.
= (70/100) x 90
= (70*90)/100
= 6300/100
= 63
You have 10 gallons of lemonade to sell. (1 gal ≈

What are the two equations for a cone's volume?The volume of cone is calculated using the formula (1/3)r2h, where "h" stands for the cone's height and "r" for the base radius. As a result, (1/3)r2 is the cone's volume in terms of the slant height "L." (L2 - r2).
Volume of a cone:Volume of a cone is given by the expression,
V = 1/3πr²h
Here,
r = radius of the cone
h = Height of the cone
Radius of the cone = = 4 cm
Height of the cone = 11 cm
Amount of lemonade = 10 gallons
Volume of one cone = 1/3π(4)²× 11
= 184.307 cm³
Covert the gallons into cubic cm,
∵ 1 gallon = 3785 cm³
∴ 10 gallons = 37850 cm³
∵1 cones are represented by a volume of 184.307 cm3.
∴ 1 cm³ will represent the volume = 1/184.307 cup
∴ 37850 cm³ will represent the volume = 37850/184.307 cups
= 205.36 cups
= 205 cups
Therefore, number of packs of cups to be bought = 205/50
= 5 packs
b). If 80% of the lemonade are sold, amount of lemonade sold = 10 × 80/100
= 8 gallons
Volume of 8 gallons lemonade in cm³ = 8 × 3785
= 30280 cm³
Therefore, number of cups to be used = 30280/184.307 cups
= 164.29 cups
≈ 164 cups
Number of cups purchased = 250
And there are 250 cups left after subtracting 164.
= 86 cups
Therefore, number of cups remaining are 86 cups.

what is the period of the sinusoidal function? enter your answer in the box.
The graph would replicate itself starting at (0,0) if we wanted to start there (4,0).
What is meant by sinusoidal function?A sine function, a periodic function that oscillates smoothly between high and low values, serves as the foundation for a sinusoidal function. Cosine functions can also be used as the foundation for sinusoidal functions because they are essentially a horizontal shift of sine functions.
We must establish the amplitude, period, and vertical shift of the periodic phenomenon in order to establish a sinusoidal function that models it. Determining whether to utilize a sine or a cosine function and the ensuing phase shift is also necessary.
The interval over which the graph repeats itself can be inferred from the graph. The graph would replicate itself starting at (0,0) if we wanted to start there (4,0). So, four is the era.

What is equation?A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.

that he makes:
• exactly 3 of the 5 shots? • exactly 4 of the 5 shots? • all 5 shots? • 3 or 4 of the shots?
a) The probability that the player makes exactly 3 of the 5 shots = 0.3087
b) The probability that the player makes exactly 4 of the 5 shots = 0.36015

What is a Binomial Distribution?The binomial distribution is a type of probability distribution that predicts the likelihood of obtaining one of two outcomes given a set of inputs. It summarizes the number of tries where each trial has the equal chance of producing the same result.
The formula for Binomial Distribution is given by
P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ
where
n = number of trials
x = number of successes
p = probability of getting a success in one trial
q = probability of getting a failure in one trial
q = 1 - p
Given data ,
Let the probability be represented as P
The total number of trials n = 5
The probability of getting a success p = 0.70
The probability of getting a failure q = 0.30
Now , the equation will be
a)
The probability that the player makes exactly 3 of the 5 shots = A
P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ
n = 5
x = 3
Substituting the values in the equation , we get
A = ⁵C₃ ( 0.70 )³ ( 0.30 )²
A = 10 ( 0.343 ) ( 0.09 )
A = 0.3087
So , probability that the player makes exactly 3 of the 5 shots is 0.3087
b)
The probability that the player makes exactly 4 of the 5 shots = B
P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ
n = 5
x = 4
Substituting the values in the equation , we get
B = ⁵C₄ ( 0.70 )⁴ ( 0.30 )¹
B = 5 ( 0.2401 ) ( 0.3 )
B = 0.36015
So , probability that the player makes exactly 4 of the 5 shots is 0.36015
c)
The probability that the player makes all 5 shots = C
P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ
n = 5
x = 5
Substituting the values in the equation , we get
C = ⁵C₅ ( 0.70 )⁵ ( 0.30 )⁰
C = 0.16807
So , probability that the player makes all 5 shots is 0.16807
d)
The probability that the player makes 3 or 4 of the shots = D
D = A + B
D = 0.3087 + 0.36015
D = 0.66885

Step-by-step explanation:
Answer:
Rs 20
Step-by-step explanation:
S.P. (Selling Price) is the price at which a product is sold. C.P. (Cost Price) is the price at which a product is purchased. When S.P. is greater than C.P., it results in a profit. To calculate profit, the formula is simple:
Profit = S.P. - C.P.
In this case, S.P. is Rs. 210 and C.P. is Rs. 190. So, the profit would be calculated as:
Profit = Rs. 210 - Rs. 190 = Rs. 20.

first, you can say that QRP is similar to PRS
with the ratios, you can say that
[tex]\frac{QR}{PR} = \frac{PR}{RS}\\[/tex]
by substituting values, you have
[tex]\frac{6}{PR} = \frac{PR}{18}\\[/tex]
[tex]PR^2=108[/tex]
[tex]PR=6\sqrt{3}[/tex]
using pythagorean theorem, you can determine that
[tex]PS^2=(6\sqrt{3})^2+18^2[/tex]
[tex]PS^2=432[/tex]
[tex]PS=\sqrt{432}=12\sqrt{3}[/tex]
Answer:
12√3
Step-by-step explanation:
cos∠RSP = 18/PS
cos∠PSQ = PS/24
∠RSP=∠PSQ (the angle at S)
18/PS = PS/24
(PS)² = (18)(24) = 432
PS = √432 = 12√3
